DIAMOND DRILLING This is and interesting little booklet that I picked up at a local flea market that maybe of interest to serious  oil folks. It is not from Petrolia Ontario but is of interest. It is here for you. Let me know if you liked it. . All of these pics and more are from my own collection and from our contributors. If you would like to become a contributor, I just need a few minutes to scan what you have. Email Martin martyd@ebtech.net
